有什么办法建立在不同的数据库触发器？我的要求是这样的： -

Is there any way to create triggers on different databases? my requirement is like:-

 database: a1.db consist table: t1
 database:a2.db  consist table: t2

现在我必须在T1使用触发器（无论任何删除和更新操作）在t1上发生的值已经被插入到T2。

now i have to use trigger on t1 (whenever any delete and update operation) happens on t1 a value has to be inserted into t2.

在等待您的反馈...

推荐答案

我只能说针对MySQL的，但你应该能够做到这样的：

I can only speak for MySQL, but you should be able to do something like:

CREATE TRIGGER ad_t1 AFTER DELETE ON `a1.db`.t1
FOR EACH ROW
INSERT INTO `a2.db`.t2 VALUES (...)
